MetroMail is an email application for Windows 8 that supports only Gmail. While that is not ideal if you manage multiple email accounts from different providers, it may be interesting to Gmail-only users.

The application supports major Gmail specific features such as labels, archiving, or inbox categories that Google introduced some time ago.

It synchronizes data between devices, and can be used on Windows 8 and Windows Phone 8 devices. If you bought the app on Windows Phone, you can generate a code to unlock the Windows 8 version for free.

Other features include support for multiple accounts, support for advanced Gmail search operators, or support for sending and downloading email attachments.

The app can be used free for 30 days. Ads are introduced after that period, and push notifications are disabled. While it is still possible to use the app this way, you can also purchase it to remove the ads and enable the notifications again.

Triangula is a puzzle game that you can play against another human opponent or the computer.

The goal of the game is to fill out the game board by completing triangles on it. You can connect two dots on the board each turn, and when that last connection creates a triangle, it is filled in your color.

You do need to draw another line afterwards though and that continues until the board is completely filled.
